TIPPLE FOR COAL-CARS.

Specification of Letters Patent.

Patented June 29, 1909.

Application filed August 25, 1908. Serial No. 450,231.

To all whom it may concern:

Be it known that we, WILLIAM L. HANSEN and ALFRED HAYES, citizens of the United States, residing at Coalville, in the county of Summit and State of Utah, have invented a new and useful Improvement in a Tipple for Coal-Cars, of which the following is a specification.

This invention is an improvement upon the automatic dum ing device for which we obtained Letters atent April 17, 1906, No. 817,972, and March 10, 1908, Number 881,316. 1

The invention consists in the novel features of construction hereinafter described, pointed out in the claims and shown in the accompanying drawings, in which- Figure 1 is a plan view. Fig. 2 is a side elevation, a supporting frame being shown in section. Fig. 3 is a section on the line 3-3 of Fig. 1. Figs. 4 and 5 are detail perspective views of wheel stops. Fig. 6 is a per- I spective view of a locking bolt.

' In these drawings 1 represents an open rec tangular frame forming an 0 en dump to which lead track sections 2. n said frame is journaled a shaft 3 held in suitable bearings 4. Upon said shaft is fixed a tilting latform 5 which we have also shown in the ibrm of an open frame as it is not necessary that said platform should be solid. The platform 5 carries track sections 5 which form a continuation of the track sections 2. Adjacent each end downwardly and inwardl extending brackers 6 are carried by the p atform 5 and said brackets support a beam 6 which extends below and parallel to the platform, and serves as a counterweight for the purpose of balancing the platform to a certain extent during the dumping operation thus rendering it comfparatively easy to control the movements 0 the platform as it is rocked upon the shaft 3. The (platform also carries u rights 7 arranged a jacent the rails 5 which support bars 7 beneath which the wheels of a car run upon said platform rest when in locked position. We strengthen this construction by means of inclined brace rods 8. Bars for this same purpose are shown and their use fully explained in the patent above referred to. To give the operator perfect control over the dumping movement we provide a metal brake band 9 the end ortions of which are an led and secured to t e bars 7 the said ban curving under the platform 5 and beneath the beam 6. A sectlonal brake shoe 10 has one end portion secured to a beam 11 and the other end to a lever 12 mounted upon a bracket 13, the said brake shoe engagingthe greater ortion of the band 9, the band 9 rotating wit in the shoe as the platform is tilted. We also provide a bar 14 working through the rails 5 and having a hooked portion 14 extending normally over the tread portion of said rails. The bars 14 are connected to bell cranks 15 to which are connected operating bars 16 pivotally connected at their opposite ends to vertically movable plates 17 pivoted in brackets 17 Springs 18 are connected to end portions of the platform 5 at one end and to the bars 16 at the opposite end. These last described parts form wheel locks resembling in their operation those shown in the patents already granted.

A slidin locking bolt 19 having an upturned iucined end portion 19 is ivoted to a rod 20 which in turn is pivota y connected to an angled foot lever 21. A spring 22 is secured at one end to the frame 1 and at the other end to the foot lever.

The operation of the device is as follows: The car to be dumped is run upon the platform 5 and as the forward wheels strike the hooked members 14" they will slide the same upon the rails, thus operating the bell cranks 15, the bars 16 and throwing the plates 17 into position back of .the rear Wheels of the car, so that both front and rear wheels are provided with front and rear stops, and are also resting beneath the bars 7. The foot lever 21 is then depressed withdrawing the bolt 19 and releasing the platform 5 and as the car swings downwardly toward the right,

as seen in F 1g. 3, the counterweight 6 will swing upwardly toward the left, and the movement of the platform 5 can be slackened or completely checked by drawing back the lever 12 and tightening the sectional shoe 10 upon the band 9. When the car has been dumped the weight of the beam 6 will overbalance the empty car and by relieving the band 9 from pressure of the brake shoe 10 by hfting the lever 12 the platform will be swung back by Wei ht of the beam 6 into normal position, suc return movement bein also under control of the operator as the rake shoe 10 can be tightened at any time. As the platform 5 swings back one of its side beams strikes the angled portion 19 of the bolt 19 and forces said bolt back, the spring 22 returning it to locking position after the platform is in position to receive asecond car.-

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent, is:

1, A device of the kind described comprising a tilting platform, a counterweight beam suspended from said latform, a rigid brake band inclosing said p atform and beam and turning therewith, and a brake shoe arranged for engagement with said band.

2. A device of the ldnd described comprising a tilting platform, bars supported by said platform, said bars extending above the wheels of cars run u on said platform, a counterweight sus ended below and parallel to the longitudina center of said latform, a curved brake band having its en s fastened to the bars, said brake band passing around been the sides of the platform and counterweight beam, and a sectional brake shoe in contact with said band, said shoe being fixd at one end and movably held at the other end.

3. A device of the kind described comprising a tilting latform, a curved metal band having its en ortions supported above the platform, 'said and assing aroundthe sides of the platform and neath the platform, a counterweight suspended below the platform and within the band, said 'wei ht being arranged transversely to the banc l, a sectional' brake shoe secured to a thick support at one end, and a lever ivotally connected to, the other end of said s ime.
